The Pilgrim Nuclear Power Station is back online.
The Plymouth station re-connected to the grid Wednesday evening just before 6:30.
Pilgrim had shut down on January 4 following the loss of one of the two offsite 345-kilovolt Eversource-owned transmission lines to which the plant feeds its power.
During the time the plant was offline, workers took the opportunity to perform maintenance that cannot otherwise be done while the plant is operating.
